The noise drilled his ears. He held his breath, waiting, tense. Then he lowered his arm, and the others sucked air and dove. Again Jack lowered his face to eye level with the water.
The jet ski roared up to the opening of the side channel, but the driver, a clone of the other, maintained a watch on the larger island across the canal. Standing, the man had a hand pressed to an ear, listening to his radio, reporting in. His words were muffled by the jet ski’s engine.
Jack willed him to continue past.
As if hearing his silent plea, the man swung around. Jack just barely managed to duck underwater in time. From under the surface he stared up. He could see the man’s watery image, saw him pause, floating the jet ski in place.
Jack felt Karen tug on his hand. She and the others were running out of air. He squeezed her hand, then released his grip and slipped away from her side. Karen tried to grab the back of his shirt, but he knocked her hand aside.
Overhead, the jet ski turned in their direction. Jack saw the man reach for his rifle. Exhaling slowly, Jack sank deeper. He slid out of the side channel, scuttling under the starboard edge of the ski. He hated to abandon the others, but he needed a moment’s distraction.
Crouching down on the bottom of the canal, he positioned his feet and squinted up. C’mon, he urged the others. Then he heard a frantic kicking as one of his group ran out of air and was forced to surface.
Jack did not wait. He shoved with all the strength in his legs and shot out of the water.
The driver, still facing the channel, had his weapon pointed in the wrong direction. He noticed Jack’s attack a moment too late.
Jack knocked him off the jet ski’s seat. The man grabbed the handlebars and twisted around, but by then Jack’s elbow had smashed him in the face, crushing his nose, driving the bone into his brain. Instant death.
Jack did not pause. His old instincts arose. He relieved the guard of his rifle and radio headpiece, then shoved the man into the canal.
As he swung back into the jet ski’s seat he found Karen staring up in shock from the canal.
“Kill or be killed,” he grumbled, then gunned the jet ski. “C’mon.”
Karen held out a hand, and Jack pulled her into the seat behind him. There was not enough room for the other two.
“Grab the edge of the jet ski,” he instructed them. “I’ll drag you both.”
Miyuki and Mwahu swam to either side, fingers clutching for handholds.
“Ready?”
“Y-Yes,” Miyuki said, shivering.
Jack edged the ski forward. Over the noise of his own watercraft he heard the growing roar of the other jet ski. He increased his pace, but a squeal of protest from Miyuki forced him to throttle down. The professor gagged out a mouthful of seawater.
“Sorry,” he said, twisting around and watching for the other guard. Jack clutched the handles in a tight grip. “We can’t outrun them like this.”
Karen nodded down the canal. “What about Mwahu’s tunnel?”
They should have just enough time, Jack thought, and slowly throttled up. “Hold your breath.”
Gliding the jet ski, he headed toward the islet Mwahu had pointed out. Once abreast of it, he ducked the ski into another side canal and parked it out of sight.
“Is this the place?” Karen asked Mwahu.
Half drowned, the islander indicated the rear side of the islet’s single squat building.
Shouldering the rifle, Jack hopped to shore and helped the others up onto the weed-choked island. He quickly led them around the building, where he stumbled to a stop. “Goddamn it!” The entrance to the building was blocked by a large basalt boulder. He sagged and turned. “Is this your entrance to the tunnels?”
Mwahu crossed and placed a hand on the boulder. He looked near tears. Answer enough.
Karen joined the islander. “We can move it,” she said, wiggling out of her wet pack. “It’s basalt. We have the crystal.”
Jack looked at the boulder. It was deep in shadows as the sun hovered at the horizon. “We need sunlight.”
Karen passed him the crystal. “I’ll get it for you.” She removed a plastic compact from her pack, opened it and broke off the mirror. Stepping back to the corner, she aimed the mirror toward the sun and deflected a beam toward the boulder so a spot of sunlight danced on the boulder’s surface.
Jack smiled. “It’s worth a try.”
He crossed to the boulder and slapped on the star, still sticky with gum. It failed to adhere to the uneven surface, but he found he could hold it in place and push with his shoulder. He nodded to Karen.
It took her a few tries to hit the star with the reflected sunlight. Jack pushed each time the star burst with radiance. The boulder, much more massive than the crypt’s lid, was still heavy. Jack dug in his heels, straining against the rock, fighting it. Mwahu joined him and pushed, too. Slowly, the boulder shifted.
“I don’t hear the other jet ski,” Miyuki said.
Jack paused. She was right. Silence lay over the ruins. “He must have discovered the body. He’s probably reporting in.” He hunkered down again. “C’mon, we’re running out of time.”
Karen tilted her mirror. The star flashed brilliantly. Jack and Mwahu groaned, against it. The boulder rolled a full foot. The gap opened enough for a small person to crawl inside.
“That’ll have to do,” Karen said. “We can squeeze.” She passed Jack her pack and crouched down, slithering into the space. Once through, she called back. “Mwahu was right. There is a tunnel. It leads steeply down from here.”
Jack waved for Miyuki and Mwahu to follow. The pair quickly squeezed inside, into the stone building, while Jack backed to the far side of the boulder. The stone’s far edge, now pushed beyond the shelter of the building, was bathed in sunlight.
“Now you,” Karen called out to him. “Jack?”
He hooked Karen’s pack to his own shoulder and placed the crystal star against the sunlit edge of the boulder.
“Jack?”
The crystal glowed brightly. Jack crouched down and shoved against the boulder, legs straining. The large stone rolled back into the shadows. Then he straightened and walked back around. Without sunlight, the boulder was now impossible to move any farther.
“What are you doing?” Karen asked from the other side. The crack was no wider than the palm of his hand. Her face was pressed to the gap.
“We can’t leave the way open,” he said. “They’ll find the jet ski and quickly discover the opening. They’ll hunt us in the tunnels.”
“But—”
The roar of a jet ski echoed over the water. First one, then another, then another.
“They’re coming,” Jack said, standing. “I’ll try and lead them away.” He stepped back and tucked the crystal into the pack on his shoulder. “But if they catch me, I’ll have what they want — the crystal. Either way, they should leave you all alone.”
“Jack…” Karen wiggled a hand through the crack.
Jack knelt and took her hand. “Try to get to someone in authority.”
Karen nodded, eyes moist. “I will.”
Jack turned her hand and gently pressed his lips to her palm. “I’ll see you soon.”
She closed her hand, savoring his kiss. “You’d better.”
Jack pushed back up. There was nothing else to say. He hitched Karen’s pack higher on his shoulder and hurried to the lone watercraft. The screams of the other jet skis echoed across the ruins.
Jack settled into the jet ski’s seat, hooked the radio headset in place and strapped the assault weapon over his shoulder. Ready, he gunned the jet ski, adding its voice to the chorus of others. Opening the throttle, he shot forward.
Across Nan Madol the sun was sinking below the horizon. As darkness descended, Jack remembered Mwahu’s earlier warning.
An old superstition.
Death lay among the ruins at night.
David Spangler stood atop the stone roof of the central keep, one of the tallest points in Nan Madol. He had a comprehensive view of the entire megalithic city. Using a night vision scope, he watched the chase begin. He saw Jack’s jet ski suddenly burst from out of hiding behind one of the islets.
